Caltech Engineering Services India is a leading manufacturer for cathodic disbondment test instrument. Cathodic disbonding tester is designed to test and accurately determine the characteristics of insulating coating systems applied over steel material. It can be used for epoxy coated steel reinforcing bars. Cathodic disbondment test equipment has high accuracy in potential (measured and applied), limits of deviations between the actual and reported. CD Tester is one of the useful instruments to test and determine accelerated corrosion testing of insulated coatings over steel surface. Cathodic disbondment test equipment is manufactured with latest microprocessor based technology with multi-channel based on potentiostat operations. The instrument is highly user friendly. No need of factory training. In electrochemical process, a potentiostat is a controlled and measured device in an electrolytic cell, keeps the potential of the working electrode at a constant level with respect to the reference electrode. It consists of an electric circuit which controls the potential across the cell by sensing changes in its resistance, varying accordingly the current supplied to the system: a higher resistance will result in a decreased current, while a lower resistance will result in an increased current, in order to keep the voltage constant.
